ALEXANDER KAHANOWICZ, OF NEW YORK, N. Y.

SELF-REGISTERING MEASURING-RULE.

T 0 all whom it may concern:

Be it known that I, ALEXANDER KAHANo- WICZ, a subject of theAustro-I-Iungarian Emperor, residing at the city of New York, county andState of New York, have invented a new and useful Self-RegisteringMeasuring-Rule, of which the following is a specification.

This invention relates to a measuring rule which is so constructed thata count of the yards or other lengths measured off may be mechanicallymaintained, so that the operator is relieved from mental strain and isnot liable to make a miscount.

In the accompanying drawing: Figure l is a front view partly broken awayof a measuring rule embodying my invention, and Fig. 2 is a right handend view thereof.

The measuring rule comprises a graduated stick 10, which is somewhatshorter than the measuring length of said rule, and to one end of whichis secured a casing 11, having the same cross sectional configuration asthe stick 10, the aggregate length of stick and casing constituting themeasuring length of the rule.

Within casing 11, there is wholly housed a counting mechanism, theconstruction of which does not constitute part of the present invention,the units, tens and hundreds of said mechanism, being adapted to beexposed through corresponding openings or windows 12 of the casing. Thecounting Specification of Letters Patent.

Patented May 12, 1914. Serial No. 782,991.

mechanism is actuated by a push button 13, extending outwardly throughthe end plate of the casing, the construction being such, that eachpressure on said button will ad vance the count for one figure. Thereturn to zero means of the counting mechanism are operable by a fingerpiece 14: that likewise extends through the end plate of the casing.

In use the operator presses on the finger piece once as he measures offeach yard, so that he can readily ascertain the total number of measuredlengths by the figures exposed through the openings 12. In this way anymental carrying of the measured off lengths is entirely dispensed with,and mistakes are not liable to occur.

I claim:

A measuring rule comprising a measuring stick which is short of themeasuring length of said rule, a casing having substantially the samecross-sectional configuration as the measuring stick and secured to oneend thereof, the aggregate length of stick and casing constituting themeasuring length of the rule, a counter wholly housed within the casingand exteriorly accessible means on the casing for operating the counter.

In testimony whereof I aflix my signature in presence of two witnesses.
